The calibration/validation framework of microsimulation models makes use of vehicle tracking data obtained through smartphones with an embedded GPSchip.

Abstract

The main objective of this paper is to verify the capability of microsimulation to be employed in road safety analysis purposes. In particular, two different microsimulation tools (VISSIM and TRITONE) are used to analyse road safety performance of a two-way undivided highway under car-following conditions. The calibration/validation framework of microsimulation models makes use of vehicle tracking data obtained through smartphones with an embedded GPSchip. Observed vehicles’ interactions are compared to those simulated, in terms of safety performance indicators, determining how a microsimulation approach fits the real conditions.
